[CA] i60 True wind not working

[hwturn]

Thanks for the detailed reply. I have replaced or confirmed operational every cable and converter in the system. I now have tridata on the MFD. My wind unit is still reading apparent wind, but only dashes for true wind. Neither TW or AW will read on the MFD. Is it possible the i60 isn't talking on the network, but is able to get power? As I said i confirmed the seatalk spur cable that is connected to the i60 is working as i connected it to a backup tridata and the MFD saw that. The issue seems to be specific to the i60 as everything else on the network seems to be talking.
Any ideas on what I can do to further isolate the issue or do i need to have the i60 devise bench tested?
Thanks,
